1 Claim. 1

Thi invention relates to wire tightening devices, and more particularlyto the provision of a device for tightening the wire strings of a piano.

It is an object of the invention to provide a tool for tightening a knotfor joining parts of of a wire when the Wire breaks between a pianobridge and a tuning pin.

A further object is to provide a wire tightening device which is simplein structure and easily applied, the device being of a nature thatenables it to be conveniently carried.

These and other objects are attained by the novel arrangement andconstruction hereinafter described and illustrated by the accompanyingdrawings, forming a part hereof, and in which:

Fig. 1 is an elevational view of a sounding board with the wiretightening device embodying the invention.

Fig. 2 is a plan view of the wire tightening de vice.

Fig. 3 is a side elevational view of the tightening device.

Referring to the drawings, in Fig. 1 are shown horses I, upon which aresupported a piano back frame 2, a back 3, and a sounding board 4, and. atuning block 5. A string 6 which has been broken and rejoined by tyingthe broken ends together by a knot (in is attached at one free end tothe tuning back frame 2.

The wire tightening device is shown to comprise a tubular member 8having one side out out to fit over a tuning pin 1. The tubular member 8is integral with or connected to a bar 9 having projecting up therefroma staff ID with a handle I I, the staff being provided with a hole 12adapted to receive the other free end of the wire 6.

Initially, the latter end of the wire is tightened about the staff Inwith the portion l3 of the bar at the left of the tuning pin 1 as shownin Fig. 3. The final tightening of the Wire is accomplished by rotatingthe handle portion l3 to the right as shown in Fig. 1, thus enablingfine adjustment.

The tightening device is obviously simple in structure and readiliapplicable to a tuning pin and easily removed so that it can be quicklyapplied to different wires of a piano.

The above description is to be considered as illustrative and notlimitative of the invention, of which modifications can be made withoutdeparting from the spirit and scope of the invention as set forth in theappended claim.

The invention having been described, what is claimed is:

In a wire tightening device, a bar having a handle portion and amounting portion, said portions lying in parallel planes in offsetrelation to each other and extending in opposite directions from eachother and an inclined portion joining said first mentioned portions attheir inner ends, a tube connected to the outer end of the mountingportion of the bar, in depending relation thereto, said tube having oneside thereof cut out to fit over a tuning pin of a piano so that saidbar can be rotated on the pin, a staff projecting from the mountingportion of the bar in vertical relation thereto adjacent to the inclinedportion in offset relation to the vertical axis of the tube, said staffhaving a hole therein above the mounting portion of the bar to receivean end of a wire and a handle for rotating the staff until thepreliminary tightenin of the wire is accomplished and final tighteningof the wire may be accomplished upon movement of the handle portion ofthe bar in the same direction as the handle has been rotated.
